Embodiment Construction

[0052] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0053] A monitoring method for subgrade settlement, including monitoring nodes,

[0054] The monitoring node includes a container, the container is provided with a liquid, the container is provided with a detector, and the detector is used to monitor the change of the liquid level, and transmit the monitored situation to the monitoring center;

[0055] On the subgrade to be monitored, set a monitoring node at intervals;

[0056]According to the situation of the roadbed to be monitored, determine an area for monitoring whether the roadbed is subsiding, set at least two monitoring nodes in the area, and connect the liquids in all the monitoring nodes to form a connector, through the By comparing the changes in the liquid level of each monitoring node in the above-mentioned area, it can be concluded whether t...

Abstract

The present invention discloses a monitoring method for subgrade settlement, and a device thereof. The method is characterized in that monitoring nodes are provided, wherein the monitoring node comprises a container, a liquid is arranged inside the container, the container is provided with a detector, the detector is used to monitor change of the liquid level and transmit the monitoring situation to a monitoring center, and the monitoring nodes are arranged every a certain distance on a subgrade requiring monitoring. The method and the device have the following advantages that: the measurement precision is high, no manual operation is required during the measurement process, the information can be transmitted to the monitoring center at a rapid rate, the installation and the use are convenient, and real time monitoring of large rang subgrade settlement is prompted.

Description

technical field [0001] The present invention relates to the technical field of monitoring subgrade settlement. According to an embodiment disclosed in the application document, it specifically relates to a method and device for monitoring subgrade settlement through a wireless network and ultrasonic waves. Background technique [0002] Subgrade is an important part of railway line engineering. It is the basis for bearing the weight of track structure and train load, and it is also the weakest and most unstable link in line engineering. During the construction and after the completion of the project, the subgrade will inevitably deform under the action of load and other factors, resulting in uniform or uneven settlement. Post-construction settlement, especially uneven settlement, is likely to cause cracking, skewing and damage to the main structure of the railway, and may also have a certain impact on the surrounding buildings and underground pipelines. Therefore, considerin...
